Description

Technical Field

[0002] With the development of heat dissipation technology, liquid cooling is gradually introduced to the market, and immersion gas-liquid two-phase flow liquid cooling belongs to the cutting-edge technology of liquid cooling technology. The working principle of immersion two-phase flow liquid cooling is as follows: the heat source is directly immersed in the insulating coolant liquid, the heat source generates heat, and the heat is dissipated in the liquid in contact with the heat source. After the liquid is heated, it boils (the boiling point of the insulating coolant liquid has various options, ranging from 40°C to 120°C) and takes away the heat. After the steam rises, it meets the condenser tube, condenses on the condenser tube, and then flows back to the liquid cavity, circulates back and forth to achieve thermal balance;

[0003] However, when the device is in use, condensed water falls to a position above the coolant. The condensed water naturally sinks and mixes in the coolant for a long time, resulting in a high temperature in the lower layer and a low temperature in the upper layer of the coolant. Most of the equipment to be cooled is located in the lower layer of the coolant, resulting in poor heat dissipation efficiency of the device. Summary of the invention

[0041] Example 1

[0042] Reference Figure 1-Figure 4 , a two-phase immersion liquid cooling device is provided, comprising a cabinet 100, wherein a condensing pipe 101 is provided on the upper part of the cabinet;

[0043] The fixing part 200 is disposed inside the cabinet 100;

[0044] A moving part 300, which is disposed on the fixing part 200 and can move on the fixing part 200;

[0045] A condenser 101 is provided on the upper part of the cabinet 100. The condenser 101 is connected to a gas-converting fixed part 200 at the bottom of the cabinet 100. A movable part 300 is movably connected to the fixed part 200. When in use, the cooled device can be placed on the fixed part 200, and multiple groups of movable parts 300 are provided around the cooled device. The movable parts 300 can locate the cooled device to prevent the cooled device from moving in the cabinet 100. At the same time, the coolant can flow between the multiple groups of fixed parts 200, so that all surfaces of the cooled device can be in contact with the coolant, thereby improving the heat dissipation effect of the device.

[0046] Furthermore, the fixed part 200 includes a long plate 201 disposed at the inner bottom of the cabinet 100; the movable part 300 includes a long tube 301; wherein the bottom end of the long tube 301 is plugged into the outer side of the long plate 201;

[0047] The long board 201 is fixed at the bottom inner side of the box body, and multiple groups are equidistantly arranged. Multiple groups of long pipes 301 can be arranged on one group of long boards 201, and the long pipes 301 can be arranged at any position on the long boards 201 as needed. When in use, multiple groups of long pipes 301 can be arranged around the cooled equipment, and then the long pipes 301 can be used to position the cooled equipment to avoid displacement of the equipment. When multiple groups of cooled equipment are arranged in the cabinet 100, the distance between the two groups of equipment can be adjusted by the long pipes 301 to improve the heat dissipation effect.

[0048] Furthermore, the long tube 301 is provided with a through slot 301a corresponding to the long plate 201, and a clamping block 302 disposed in the through slot 301a; the long plate 201 is provided with a clamping slot 202 corresponding to the clamping block 302;

[0049] The clamping groove 202 cooperates with the clamping block 302 to limit the position of the long tube 301 on the long board 201;

[0050] A through slot 301a is provided at the bottom end of the long tube 301, and the width of the through slot 301a corresponds to the width of the long board 201. A clamping block 302 is fixedly provided on the inner wall of the through slot 301a of the long tube 301. The long board 201 has multiple groups of clamping slots 202 corresponding to the clamping block 302. The engagement of the clamping slots 202 and the clamping blocks 302 enables the long tube 301 to be plugged into the long board 201 without sliding along the long board 201, and the position can be fixed.

[0051] Furthermore, a baffle 203 is fixedly connected to the top of the long plate 201; a long groove 204 is opened near the end of the long plate 201; the long groove 204 enables the long tube 301 to be sleeved with the baffle 203;

[0052] A baffle 203 is fixedly provided at one end of the top of the long plate 201, and the cooled equipment is placed on the top of the baffle 203. There is a gap between the bottom of the baffle 203 and the top of the long plate 201, and cooling water can flow through the gap at the bottom of the equipment, thereby improving the heat dissipation effect. The width of the baffle 203 is consistent with the width of the through groove 301a, so that the long tube 301 can be limited after being sleeved therewith and can only move up and down. The length of the baffle 203 is less than the length of the long plate 201, so that there is a gap between the end of the baffle 203 and the end of the long plate 201. At the same time, a long groove 204 is opened at the end position of the long plate 201. When the long tube 301 is plugged into the long plate 201, it is first inserted into the long groove 204 through the gap, and then moved toward the slot 202, so that the long tube 301 is sleeved with the baffle 203.

[0053] Furthermore, an elastic member 304 is provided inside the block 302, and the elastic member 304 extends out of the top thereof; when the long tube member 301 is plugged into the outside of the long plate 201, the top of the elastic member 304 abuts against the bottom of the baffle 203;

[0054] A limiting groove 303 corresponding to the elastic member 304 is formed in the block 302. The elastic member 304 includes a limiting rod 304a slidably disposed in the limiting groove 303. A circular plate 304b is fixedly disposed on the top of the limiting rod 304a. A first spring 304c is disposed in the limiting groove 303. The top of the first spring 304c abuts against the bottom of the limiting rod 304a.

[0055] After the long tube 301 is sleeved with the baffle 203, the baffle 203 is located above the circular plate 304b. Since in this embodiment, the depth of the long groove 204 is greater than the depth of the clamping groove 202, when the long tube 301 needs to be fixed on the long plate 201, the long tube 301 needs to be pulled upward, and the top of the circular plate 304b contacts the baffle 203 and then slides downward. At this time, the first spring 304c is contacted and contracted. After the bottom of the clamping block 302 is separated from the long groove 204, the long tube 301 is moved outside the baffle 203, and the clamping block 302 moves in the gap between the baffle 203 and the long plate 201.

[0056] When the long tube 301 moves to the desired position, the clamping block 302 is aligned with the clamping slot 202, and the long tube 301 is released. At this time, the first spring 304c pushes the circular plate 304b to contact the baffle 203 through the limiting rod 304a, and the clamping block 302 moves downward and clamps with the clamping slot 202. The setting of the elastic member 304 enables the long tube 301 to be more stably plugged with the long plate 201 and fix its position;

[0057] By setting the fixing part 200 and the moving part 300, the device can be fixed at any position in the cabinet 100, and the device is placed on the top of the fixing part 200, so that cooling water can flow around the device to improve the heat dissipation effect.

[0058] Example 2

[0059] After being cooled into condensed water by the condenser 101, the steam will directly fall on the top of the cooling liquid below, resulting in a situation where the temperature of the upper layer of the cooling water is low and the temperature of the lower layer is high, and the heat dissipation efficiency is low.

[0060] Reference Figure 1-Figure 4 , this embodiment is different from the first embodiment in that: the long tube 301 is tubular with a cavity inside; a duckbill valve structure 400 is provided in the cavity of the long tube 301;

[0061] In this embodiment, the long tube 301 is a circular tube with a cavity therein. A connecting ring is provided inside the long tube 301, and a duckbill valve structure 400 is fixedly connected thereto through the connecting ring. Side grooves 301b are provided on both sides of the long tube 301 at the duckbill valve structure 400. The opening of the side grooves 301b can ensure the closure of the duckbill valve structure 400. The duckbill valve structure 400 prevents cooling water from entering the long tube 301. When condensed water falls, part of it enters the long tube 301 and is discharged into the cabinet 100 through the duckbill valve structure 400, where it mixes with the lower layer of coolant. When the condensed water falls, part of it is located in the upper layer of the cooling water and part of it is located in the lower layer of the cooling water. The condensed water can evenly return to the cooling water, thereby improving the heat dissipation efficiency.

[0062] Furthermore, a guide member 305 is provided inside the long tube member 301 and above the duckbill valve structure 400; the guide member 305 is fixedly provided on the inner wall of the long tube member 301. In the present embodiment, the guide member 305 is an inverted cone member with an opening at the bottom, and the guide member 305 corresponds to the duckbill valve structure 400, so that condensed water can enter the duckbill valve structure 400 in a more concentrated manner.

[0063] Furthermore, a collecting piece 500 is connected to the top of the long tube member 301; the collecting piece 500 includes a funnel portion 501, a connecting portion 502 is fixedly provided at the bottom of the funnel portion 501, and the connecting portion 502 is communicated with the funnel portion 501, and the collecting piece 500 is detachably connected to the long tube member 301 through the connecting portion 502, such as by threaded connection, bolt connection, etc., so that when necessary, the collecting piece 500 can be removed, or the collecting piece 500 with a funnel portion 501 of a different diameter can be replaced, the funnel portion 501 of the collecting piece 500 allows more condensate to enter the long tube member 301, and at the same time, the outer edge of the funnel portion 501 can guide the condensate, so that the condensate that has not entered the long tube member 301 can be evenly dispersed in the upper layer of the cooling water.

[0064] By providing the duckbill valve structure 400, the condensed water can be evenly mixed into the coolant, thereby improving the cooling efficiency.

[0065] The rest of the structure is the same as that of Example 1.

[0066] Example 3

[0067] In the above embodiment, since the width of the block 302 is relatively large and the sizes of the cooled devices vary, the outer side of the long tube may not fit the surface of the device during use, so that the device cannot be stably positioned.

[0068] Reference Figure 1-Figure 6 , this embodiment is different from the above embodiment in that: an adjusting component 600 is further provided on the outside of the long tube 301, which includes a cam member 601; the cam member 601 can rotate on the outside of the long tube 301, and the cam member 601 can contact the outer wall of the device;

[0069] The adjusting component 600 includes a cam member 601, and a protrusion member is arranged on the outside of the long tube member 301, which can rotate along the axis of the long tube member 301. When the long tube member 301 is arranged around the cooled device, the cam member 601 can be rotated so that its surface contacts the periphery of the device and then fixed. At the same time, an elastic pad on one side can be covered around the cam member 601 to enable it to better fit the device and fix it.

[0070] Furthermore, the adjustment mechanism further includes a positioning member 602, which is located outside the long tube member 301; the positioning member 602 can fix the position of the cam member 601;

[0071] The positioning member 602 is fixedly disposed outside the long tube member 301 and is located above the cam member 601. In this embodiment, the positioning member 602 is gear-shaped, and a gear groove 601a corresponding to the positioning member 602 is formed at the top of the cam member 601.

[0072] A reset member 603 is provided below the cam member 601. The reset member 603 includes a fixed cylinder 603a fixedly arranged outside the long tube member 301. The gear member is provided with a guide groove 601b corresponding to the fixed cylinder 603a. The gear member is sleeved with the fixed cylinder 603a through the guide groove 601b. A second spring 603b is provided in the fixed cylinder 603a. The top of the second spring 603b contacts the cam member 601, so that the cam member 601 is sleeved with the positioning member 602, and the cam member 601 can be fixed in position.

[0073] When in use, pull the cam member 601 downward to disengage it from the positioning member 602, and then rotate the cam member 601 so that its periphery contacts the outside of the device. After the cam member 601 contacts the device, release the cam member 601, and the second spring 603b pushes the cam member 601 to slide upward and reset, and then engage with the positioning member 602, so that the cam member 601 can press against the outside of the device to fix it.

[0074] Furthermore, in this embodiment, the adjustment component 600 can be set on the outside of the long tube 301 in an adjustable fixed manner, so that when the weight of the cooled device floats up easily, the cam member 601 is moved to the top of the device, and then the cooled device can be fixed.

[0075] By setting the adjustment component 600, devices of various specifications can be fixed in multiple directions, thereby improving the versatility of the device.

[0076] The rest of the structure is the same as that of Example 2.
